From 97608e4cc03082e7b1d91efd720b3104c0ba2566 Mon Sep 17 00:00:00 2001 From: Erwan Gouriou Date: Wed, 9 Jul 2025 15:11:54 +0200 Subject: [PATCH] boards: stm32n6570_dk: Disable cache on PSRAM For unclear reason yet, cache activation on PSRAM causes stability issues when using LTDC. Disable cache for now. We'll re-enable once the issue is better understood and fixed.
